Pin Definitions and Functions
Supply voltage;
external blocking capacitor necessary (see
Figure 4).
Voltage Sense Input;
non inverting with respect to voltage
compensation VCO; internal compared with the high accuracy
bandgap-reference (typ. 2.5 V).
Output;
NPN emitter follower output with an internal series resistor
of 1 kΩ; controlled by the potential of VCO or CCO; output voltage
is internally clamped therefore the output current is internally limited.
Current Sense Input 1;
connected to an internal voltage divider
(reference to the inverting input of the current OTA; see
Figure 7).
Ground;
reference potential unless otherwise specified.
Current Compensation Output;
internal series resistor to the
current-OTA output (typ. 1 kΩ); amplification internal temperature
compensated; current loop compensation can be done by an
external capacitor to GND.
Voltage Compensation Output;
internal series resistor to the
voltage-OTA output (typ. 1 kΩ); amplification internal temperature
compensated; voltage loop compensation can be done by an
external capacitor to GND.
Current-OTA Reference Input;
current sense reference input; non
inverting input of the current-OTA.
